1 Claim.

' This invention relates to windows in which the opening is provided with vertically slidable sashes, respectively inner and outer.

In order to provide a clear space between the sash frames, as for the passage of large articles,

} it is desirable at times, to completely remove the sash from the window; also when it is required to obtain the utmost in ventilation.

It is therefore an object of the invention to provide a window capable of having its sashes displaced from their frame but without actual separation or disconnection of the counterbalancing weights usually employed.

A further feature is in the provision of means whereby the sash may be swung at angles inwardly to permit cleaning of both sides of the window panes in an easy, effective manner, all danger being avoided.

Another purpose is to produce an eifective locking means for the sash when closed.

These and other advantageous objects, which will appear as the description progresses, are accomplished by the novel and practical construction, combination and arrangement of parts hereinafter described and illustrated in the accompanying drawings, constituting a material component of this disclosure, and in which- Figure 1 is a perspective view of an embodiment of the invention, parts being in section and others omitted, both sashes being shown in closed position.

Figure 2 is a similar view of the same, but showing the lower sash inturned.

Figure 3 is a perspective view of the lower, locking bolt.

Figure 4 is a side elevational view of the sash hook releasing catch.

Figure 5 is a longitudinal sectional view of the same.

Figure 6 is a fragmentary top plan view of lower sash and its lateral guide strip.

Figure 7 is a side elevational view of the same as in engagement with its guide member.

Figure 8 is a top plan view of the guide memher in detail.

Figure 9 is a longitudinal sectional view of the same, taken on line 99 of Figure 8.

Figure 19 is a side elevational view of the same.

Figure 11 is a similar view looking from the opposite, inner side.

Figure 12 is a top plan view of the lower section of the guide member.

Figure 13 is a longitudinal sectional view of the same, taken on line I3l3 of Figure 12.

Figure 14 is a side elevational View thereof looking from the outer side.

Figure 15 is a similar view looking from the inner side thereof.

Referring in greater detail to the drawings, the conventional window frame shown in Figures 1 and 2 consists of a sill 20, on which rests the lower end of facing uprights 2l-22, which form outside elements of boxes in which two pairs of weights 23 and 24 operate, one pair each for the upper and lower sashes respectively 25-26. Set in the right hand end of the lower sash element 28 is a bracket 29, in which a lock bolt slidably is mounted, actuated by a finger knob 3 I, extending through a slot 29 centrally in face of the bracket 29. The forward protruding end of the lock bolt 30 is engageable within a metal socket 32, set permanently in an auxiliary frame bar 33, which projects upwardly for approximately onethird the full heighth of the sash, and abuts the lower end of element 34 to which is attached an upper element 39, secured by the spring hook 43. Element 34 has attached the knotted lower end of a cord 35 running over pulleys 3E, setin the box frame and attached at its opposite end to one of the weights'as 23. i

The upper and lower sashes 2526 each have affixed to their respective right and left hand side edges, in opposed relation, the inturned right angled ends 38' of fiat metal strips 38, which carry on their outer faces channelled guide bars 58, of such length as to contact the adjacent ends cf the auxiliary bars 33, thus locating the bars and preventing them from moving upwardly.

The metal strip 38 is used to attach the parts to sashes being remodeled andis also used for new sashes.

Elements 33-34 are slidably engaged in the channeled guide 58. l

A metal facing 40 on the strip 34 has an inturned end 4| set in a recess 42, in the lower end of the element 3 1 and is engageable by a spring pressed hook 43 pivoted in the lower element 33 as at 44; the hook being disengaged by pressing upon a spring extended detent 45, slidable within a face plate 46 formed with a socket 41 and having in its upper portion a slot 48 in which a pin 69 is movable, the pin being rigidly set in the detent 55 which is thrust outwardly by a coil spring 58, inclosed in the lower portion of the socket. The detent is provided with a bevelled face 5|, engageable with the inside edge of the hook 43, in a manner to move it outwardly when the detent is depressed.

7 element 2 I, is engaged in a corresponding recess in a bracket 56, carried on the opposite side of the sash frame, at which time, the sash may be swung outwardly, as best indicated in Figure 2, and correspondingly, the upper sash is treated in the same manner, but hooked on the opposite side of the frame.

Thus, it will be seen that the entire space between the elements of the window frame will be clear and void of all obstructions, permitting passage of articles limited only by the size of the object to be entered or removed as may be desired.

In Figure 2, it will also be apparent that either or both of the sashes may be swung inwardly in opposite directions, allowing free and unrestricted approach to both sides, as in cleaning, or removing the glass as may be desired.

Although the foregoing is generally descriptive of the preferred form of the embodiment of the invention, it is obvious that minor changes might be made within the scope of the appended claim.

Having thus described the invention, what is claimed as new and sought to secure by Letters Patent is:

In a window having a slidable sash and a frame therefor, an upper and lower sectional guide strip fixed on one side of said sash, a catch in the upper section, a hook on the lower section 'engageable with said catch, means carried by said lower section to disengage said hook from the catch, and a bolt slidably carried by said sash to engage the lowersection of said guide strip.
